The HABApp documentation states not to use time.sleep but run.once.
I have a rule running flawlessly that shuts down the espressomachine after 2,5 hours of idle running that uses a countdown timer.
Now I would like to write rules to reset bindings that go offline. The Velux binding is a known example. Resetting is described here.
The procedure involves shutting down the bridge (power supply off), disabling the bridge, wait some second, then turn power on again, wait again for eleven minutes and enable the bridge.
No complicated functions are necessary, just plain power off and on commands after several seconds, and device disable and enable.
Not sure how this would work I wrote some simple code to see if a simple print command would function after some waiting period defined by run.once. It does not. I get the following error:
TypeError: Callable or coroutine function expected! Got "None" (type NoneType)
My code is as follows:
import HABApp
class Test(HABApp.Rule):
def __init__(self):
super().__init__()
self.run.soon(print('Counting to five:'))
self.run.countdown(5, print('Waited five seconds.'))
Test()
So I changed it to the following code, thinking that the print function was not allowed and a call to a function was needed. That, unfortunately, did not help.
self.run.soon(print('Counting to five:'))
self.run.once(5, self.after)
def after(self):
self.print('Waited five seconds.')
Nor does trying the simple form of my espresso timer script.
self.run.soon(print('Counting to five:'))
self.cd = self.run.countdown(5, self.after)
def after(self):
self.print('Waited five seconds.')
self.cd.stop()
Reading back further in the traceback it looks like the first parameter (the 5 as in five seconds countdown) is incorrect.

That puzzles me greatly: I’m pretty sure that the first parameter can be given as an integer representing a number in seconds to countdown (it is in my espresso countdown rule and it works). In de docs the wording between the run.once and run.countdown functions are slightly different, and I am not sure if I am passing parameters correctly.
How should I use run.once?
For completeness: I’m running on HABApp 25.06.2
